I'm going to catch heat for this but here goes.
I was in a pinch and needed some seed starting medium and a small tray. Bought a bag of jiffy and a pack of jiffy peat trays. The jiffy mix is ok in plastic trays but in the peat trays (all I could find, was already not a fan of them) it is terrible. I was sick on two non consecutive days last week and lost seedlings on bouh days due to drying out under lights. Not giving up on the mix but ill grow in the bathroom sink before using that combo again.
I was batting a thousand with seedlings in coir and plastic. I do feel the jiffy makes a stronger root system due to drying because they have to look for water, whereas the coir stays moist.
Anyway. Not saying the mix is bad but the combo of the two dries quick and monitering moisture is a must at all times.
